What can a pebble tell us about the history of the earth? And, what are the geological tools that can unravel this mystery? On this program, Jan Zalasiewicz discussed the planet in a pebble. Topics: science, geology, pebble, planet, groks Source: Groks Science Radio Show Podcast
A huge potential for our energy needs lies at the bottom of the ocean in the form of methane hydrates. But what happens when the ocean "burps" and large amounts of natural gas are liberated into the atmosphere? On this program, MBARI scientist Charles Paull discusses how these greenhouse gases could be abruptly released.

The Gaia Hypothesis suggests that the various lifeforms on earth interact to sustain the habitability of the planet. But, could the opposite be true? Is life on earth self-destructive? On this program, Prof. Peter Ward discussed the Medea Hypothesis.

The history of ancient human civilization is mysterious almost by definition. While many archaeologists agree with the general timeline taught in school, others believe something is drastically wrong with this theory. On this episode, journalist Graham Hancock presents an alternative story of civilization’s past. using evidence from geology, archaeology, and global myths Topics: Graham Hancock, geology, archaeology, history, ancient, civilization, comet, atlantis Source: Groks Science Radio Show Podcast
Supervolcanic eruptions have the potential to drastically alter the environment and seriously affect human civilization.
